OPERA-CHAIR.

Specification of Letters Patent.

I Patented .rune 22, 1909.

Application filed April 27, 1908. ASerial No. 429,311.

To all 'whom it may concern: I

Be it knownl that I, ALBERT' R. MILNER, citizen of the United States, 'residing at Canal Dover, in the county of Tuscarora and State of Ohio, havel invented certain new and useful Improvements in Opera- Ohairs, of which the following 4is a specification.

This invention relates to' folding opera chairs, and particularly to a swiveling chair in which the seat and back will fold'automatically when thechair is not in use.

The object of the invention is to improve the connecting devices between the seat and the back to produce the foldingV action referred to. l

' A further object of the invention isI to provide an improved standard which has an inclined surface resting upon an incline on the base whereby. the chair will turn by gravity to a certain front position, ready for occupancy, but nevertheless may `be turned partly around to a side position when desired.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a side elevation of the chair folded. Fig. 2 is a similar view unfolded, or with the seat down. Fig. 3 isa front view of Fig. 1'. Fig. 4 is a detail showing the standard turned.

Referring specifically to the drawings, 6 indicates the vstandard which has at the lower end a stem 3 arranged to fit and turn in a socket 2 on the base 1. The top of the socket, and the corresponding shoulder on, the standard 6 at the upper end of the stem 3, are beveled or inclined as indicated at 23,-

so that normally the seat will by its weight tend to assume and remain inra particular front position. When the chair is turned the incline of the standard will ride up the' incline of the socket. When the cha-ir is forcibly turned the rib 4 will hit the projecting finger 5 andprevent the chair from being turned .beyond a certain distance chair will settle down and t'urn back, in consequence of its weight. The chair, therefore, cannot remain at any po'sitim'-o't-her than-the front position except when force is appliedto the chair. This feature is of admay be turned s idewise, allowing free access or passage between the chairs and form ard, and when the seat is turned down'lugs i 30 on the bracket rest on the ends 16 at the vantage in opera chairs, since the chairs top of the forks of the standard. The seat is normally raised by a lspring 214 attached at one end to the bracket and'. at'the other end to a bolt 20 between the forks of the standard, and coiled intermediately aroun'd the cross bolt 18.

The back 19 is supported by brackets 17 pivoted by a bolt 8 to ears on the back of the standard. Each bracket has anupper lug 14 and a lower'lug 12, presentedl forwardly, and the seat bracket 24 has rearwardly extending lugs 9, projecting beyond the seat pivot into the space between the lugs 12 and 14,. and in position to strike said lugs when'the seat is raised or lowered.

When the seat is lowered, the lugs 9 come in I contact with the lugs 14 and by a cam action swing the-back rearwardly to form a comfortable cha-ir. The 'backward swing is limited .by stops 7 on the standard. When l.

theV seat isswung` up, as it will be by vthe spring 21 when the sitterl rises, the lugs 9 contact with the toes Aor lugs 12 and tilt the pushing against the occupant of l. In a folding chair, the 'combination yofl a standard, and seat pivoted under the seat, the back bracket having upper and 'lower'- forwardly projecting lugs above its pivot and on opposite Asides of a straight line between the respective pivots' of thesaid brackets, and the seat bracket lhaving av lug projecting rearwardly below the seat and betweensaid lugs and arranged to strike. the same respectively and tilt the back forwardly or backwardlyand' tolock it in either position.

and back brackets 85 back forward to close'or fold the chair. A,
